Operating Manual EMI TEST RECEIVER ESIB7 - Rohde & Schwarz

Switchover to Remote Control
ESIB
Remote Control via RS-232-Interface
Setting the Transmission Parameters
To enable an error-free and correct data transmission, the parameters of the unit and the controller
should have the same setting. Parameters can be manually changed in menu SETUP-GENERAL
SETUP in table COM PORT 1/2 or via remote control using the command
SYSTem:COMMunicate:SERial1|2:... .
The transmission parameters of the interfaces COM1 and COM2 are factory-set to the following values:
baudrate = 9600, data bits = 8, stop bits = 1, parity = NONE and owner = INSTRUMENT.
Manually:
Setting interface COM1|2
½ Call SETUP-GENERAL SETUP menu
½ Select desired baudrate, bits, stopbit, parity in table COM PORT 1/2.
½ Terminate input using one of the unit keys (=ENTER).
Return to Manual Operation
Return to manual operation is possible via the front panel or via RS-232 interface.
Manually:
½ Press the LOCAL key.
Notes: Before switchover, command processing must be completed as
otherwise switchover to remote control is effected immediately.
– The LOCAL key can be disabled by the universal command LLO
(see chapter 8) in order to prevent unintentional switchover. In this
case, switchover to manual mode is only possible via remote
control.
– The LOCAL key can be enabled again by sending the control
codes "@LOC" via RS-232 (see chapter 8).
Via RS-232: ...
V24puts(port, ’@LOC’); Set instrument to manual operation.

Limitations
The following limitations apply if the unit is remote-controlled via the RS-232-C interface:
− No interface messages, some control codes are defined (see chapter 8).
− Only the Common Commands *OPC? can be used for command synchronization, *WAI and *OPC
are not available.
− Block data cannot be transmitted.
When Windows NT is booted, data are output via the COM interface because of automatic external
device recognition. Therefore, it is recommended to clear the input buffer of the controller before remote
operation of the instrument via the COM interface.
